Climate-Smart Poultry Housing in Africa: Open-Sided, Tunnel or Fully Controlled?
The house type you choose is a climate decision with a capital cost, an energy bill and a heat-stress risk attached. Here is how the three main options compare across African climate zones.

In short
Short answer. Open-sided houses are cheapest to build and cheapest to run, but they hand performance over to the weather. Tunnel-ventilated houses buy control of air speed and temperature at the cost of fans, power and backup.
Key takeaways
- Compare on three lines, not one: capital per bird place; energy per cycle at design load; and expected performance loss on the hottest days.
- House tightness (a tunnel house that leaks never reaches design air speed), insulation of roof and walls, inlet and fan control, air speed at bird level rather than nominal fan capacity, static pressure control, alarm and sensor placement, and controller quality.
- Orientation against the sun path, roof overhang and reflective roofing, ridge height, tree and shade planning, site drainage, and water-tank placement all reduce the cooling load before a single fan is bought.
- Solar changes the running cost of ventilation, not the need for reliable backup.
- State the climate design case, the target air speed and temperature, the house dimensions and bird numbers, and the power assumptions in the RFQ.
Short answer. Open-sided houses are cheapest to build and cheapest to run, but they hand performance over to the weather. Tunnel-ventilated houses buy control of air speed and temperature at the cost of fans, power and backup. Fully controlled houses add cooling, insulation and heating for the tightest performance and the highest capital and energy bill. The right answer is the one your climate, grid and market price can support — not the most advanced one.
1. Match the option to the climate case
Hot and humid (coastal, equatorial). Humidity limits evaporative cooling, so air speed over the birds does most of the work. Tunnel ventilation with adequate cross-section and a genuinely tight house is the usual answer; near the coast, specify corrosion-resistant fans, fixings and control hardware.
Hot and arid (Sahel, inland dry zones). Evaporative pads work well here because the air is dry. The maintenance problems move to dust and water quality: specify pad access, filtration, water treatment for the pad loop and a cleaning routine.
Highland and cool-season markets. The day-to-night swing is the design case. A house that must cool birds at midday still has to hold brooding temperature at night, which pushes insulation, controlled minimum ventilation and heating capacity up the budget.

Compare on three lines, not one: capital per bird place; energy per cycle at design load; and expected performance loss on the hottest days. An open-sided house with low capital can lose more in a bad heat week than the fans would have cost over a year; a tunnel house with an unreliable grid and no generator can lose a full flock in an afternoon. Model the trade-off with your own numbers in the farm cost calculator and the poultry ROI calculator.
3. The specification items that decide whether it works
House tightness (a tunnel house that leaks never reaches design air speed), insulation of roof and walls, inlet and fan control, air speed at bird level rather than nominal fan capacity, static pressure control, alarm and sensor placement, and controller quality. Cheap controllers and poor sensor siting undo good hardware.
Backup power belongs in this section: in a tunnel house in hot weather, a power cut is measured in minutes. Size the generator and automatic transfer against ventilation load, and keep an alarm path that reaches a person at night.
4. Passive measures that cost little at design stage
Orientation against the sun path, roof overhang and reflective roofing, ridge height, tree and shade planning, site drainage, and water-tank placement all reduce the cooling load before a single fan is bought. They are nearly free on a drawing and expensive to add later.
5. Solar and hybrid power
Solar changes the running cost of ventilation, not the need for reliable backup. Where the grid is weak, a hybrid design — solar for daytime ventilation load, generator with automatic transfer for outages — is the common planning shape. Size it on ventilation demand at the hottest hour, not on average consumption.
6. Turning the choice into a comparable RFQ
State the climate design case, the target air speed and temperature, the house dimensions and bird numbers, and the power assumptions in the RFQ. Without those, one bidder prices open-sided curtains and another prices a fully controlled house, and the quotes cannot be compared. Use the RFQ template builder, the cooling calculator and the capacity cost pages for Class-4 bands. Feed and disease interact with the house decision — see feed sourcing and outbreak preparedness.
